The family of David Dao has retained two attorneys - Chicago attorney Stephen L. Golan of Golan Christie Taglia and Chicago aviation attorney Thomas A. Demetrio of Corboy & Demetrio. On Tuesday, they released a statement saying he is being treated at a Chicago hospital for his injuries:

"The family of Dr. Dao wants the world to know that they are very appreciative of the outpouring of prayers, concern and support they have received. Currently, they are focused only on Dr. Dao's medical care and treatment."
